Description: | Specimen of a fossil bivalve, Janira atava, collected from the Lower Greensand Group of Cretaceous, Early Aptian - Albian age from France.
This scallop takes its name from the five (quin) main ribs (costata) that strengthen the convex (outward curving) shell. The scallop lived on a sandy seabed in shallow coastal waters. It was able to swim by clapping its two valves together to shoot out jets of water but usually only did so to escape from predators such as fish. It fed on tiny food particles that it filtered out of the water.
The specimen was found in France.
It is from the Cretaceous period (144 - 65 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Classification: Animalia Invertebrata Bivalvia Mollusca | Temporal: | Cretaceous period (144 - 65 million years ago) | Source: | Tyne & Wear Archives & Museums | Identifier: | http://www.twmuseums.org.uk/geofinder/se... | Go to resource |
